Conclusion

Now we have our functional Quote Manager application, and we can deploy it in a Java EE 8 server (GlassFish here) and store our data in a real database (MySQL).

Till now, we have mainly worked on making the application functional. Thanks to the high-level APIs of Java EE, this was not so hard, but it is important to understand what we used and what the performance implications of each element of our stack are, to be able to validate/invalidate the performance figures once you have them in your hands.
